Detrend fails

Dear experts,

I am getting an error in the detrend stage of DPARSF. I could reproduce this error many times (I didn't click any button nor interacted in any way with the software). Note that I also get some warnings that I don't know if I should be worried about.

I am running this on Matlab R2007b on a MacOSX 10.6.

Thanks in advance for your help!

Best,

Miguel
